83 * OCNotifyAllObservers() to notify all client observers that the respective resource is being
86 * @return ::OC_STACK_OK on success, some other value upon failure.

91 * This function starts receiving the multicast traffic. This can be only called
92 * when stack is in OC_STACK_INITIALIZED state but device is not receiving multicast
95 * @return ::OC_STACK_OK on success, some other value upon failure.
97 OCStackResult OCStartMulticastServer();

125 * the consumer. A NULL handle is permitted in the event where the caller
126 * has no use for the return value.
127 * @param method To perform on the resource.
128 * @param requestUri URI of the resource to interact with. (Address prefix is deprecated in
129 * favor of destination.)
130 * @param destination Complete description of destination.
131 * @param payload Encoded request payload.
132 * @param connectivityType Modifier flags when destination is not given.

137 * discovery or resource interaction is received. The discovery could be
138 * related to filtered/scoped/particular resource. The callback is
